Description

Technical Field

[0001] This application belongs to the field of wind turbine replacement technology, specifically relating to a convenient replacement device for a high-altitude exhaust system in a substation. Background Technology

[0002] With the rapid development of the national economy, the requirements for the reliability of electrical equipment in the power system are becoming increasingly stringent. The safe operation of electrical equipment is a crucial factor affecting the safety of the power system. Ensuring the safe, reliable, stable, and economical operation of these devices is of paramount importance and is the foundation for their survival and development. As an important heat dissipation and ventilation system, the fans in the high-voltage room directly affect the operational safety of high-voltage equipment. Therefore, maintaining the ventilation system of the substation is of great significance for ensuring the reliable operation of key equipment and guaranteeing its good operating condition.

[0003] The ventilation system at high altitudes in substations requires regular inspection and maintenance. The fans at the top of 110kV and above substations are 5 to 10 meters above the ground. They are fixed to the equipment with screws or installed in the equipment through fan brackets. Replacing and maintaining the fans is extremely inconvenient. When replacement is needed, all the screws must be removed before the fan can be taken off the equipment or fan bracket. After replacement, the screw installation work must be repeated.

[0004] The conventional replacement method requires removing the fixing screws, taking out the fan for inspection and patrol, and then returning the fan to its original position and fixing it with screws after the inspection. Replacing a fan takes about 50 minutes each time, which is time-consuming and inefficient. A 110kV substation has at least 5 high-altitude exhaust ventilation devices, and a 220kV substation has at least 8 high-altitude exhaust ventilation devices, which need to be inspected and repaired twice a year, resulting in a large workload for inspection and patrol.

[0005] Meanwhile, replacing high-altitude fans is a high-altitude operation, and because the fans are close to the equipment, workers are at risk of electric shock. During the replacement process, dust and harmful gases may enter the respiratory tract. Therefore, conventional replacement methods are not very safe. Summary of the Invention

[0006] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide a convenient replacement device for the high-altitude ventilation system of substations.

Detailed Implementation

[0035] The accompanying drawings provide a more detailed description of a convenient replacement device for an elevated ventilation system in a substation, but this is not intended to limit the scope of the application.

[0036] Depend on Figures 1 to 24 As shown, a convenient replacement device for a high-level ventilation system in a substation includes a quick-installation plate, a support platform, and a bottom movable component.

[0037] A quick-release plate, fixed to the bottom of the fan mounting hole 3301 on the wall 33, is used for detachable connection with the fan. To facilitate matching and connection with the quick-release plate, [the following is provided:] Figure 10 As shown, the fan is modified as follows: The fan includes a fan body 4 with a support frame 401 at the bottom. The front end of the support frame 401 is provided with a mounting groove 402, and the fan mounting component is detachably connected to the mounting groove 402.

[0038] The support frame 401 has at least two rows of support blocks 5 at its bottom. The support blocks 5 are detachably connected to the quick-release plate. The left and right sides of the support blocks 5 are recessed with snap-fit ​​grooves 501.

[0039] Depend on Figures 7 to 9 As shown, the quick-release plate includes a fixing plate 1, a fixing frame 2, and a locking device 3. Several fixing frames 2 are fixed to the fixing plate 1 at intervals. Each fixing frame 2 includes a quick-connect groove 202 with an open front end and spring grooves 201 on both sides of the quick-connect groove 202. The support block 5 slides inside the quick-connect groove 202. To facilitate the insertion of the support block 5, the opening of the quick-connect groove 202 is a flared opening 203, and the height of the fixing frame 2 is equal to or less than the height of the support block 5. The width of the quick-connect groove 202 is the same as the width of the support block 5.

[0040] The locking device 3 includes a plug block 301, a first slide rod 302, and an outer block 303 that are fixedly connected in sequence. A first spring 304 is sleeved on the first slide rod 302. A through hole is provided on the partition between the spring groove 201 and the quick-connect groove 202. The plug block 301 passes through the through hole and is placed inside the quick-connect groove 202. One end of the first slide rod 302 away from the quick-connect groove 202 passes through to the outside of the fixing frame 2 and is fixedly connected to the outer block 303.

[0041] A limiting ring is fitted onto the first slide rod 302, and a first spring 304 is disposed inside the spring groove 201, with both ends of the first spring 304 abutting against the limiting ring and the inner wall of the spring groove 201, respectively. The limiting ring is located between the first spring 304 and the insert block 301.

[0042] The partition between the spring groove 201 and the quick-connect groove 202 has a through hole with a depth greater than or equal to the thickness of the insert 301, and the outer diameter of the limiting ring is greater than the through hole. Under the push of the first spring 304, the limiting ring abuts against the partition, and the insert 301 extends into the quick-connect groove 202 and engages with the snap-fit ​​groove 501.

[0043] The outer side of the end face of the support block 5 facing the quick-connect plate is inclined, and the inner side of the front end face of the insert block 301 is also inclined; the two inclined surfaces are connected in tandem. When the support block 5 is inserted through the flared opening 203, it is guided by the flared opening 203 into the quick-connect groove 201. Continuing to slide, the inclined surface of the support block 5 abuts against the insert block 301, pushing the insert block 301 outwards. The insert block 301 moves into the through hole of the partition between the spring groove 201 and the quick-connect groove 202. The support block 5 continues to slide, and when the locking groove 501 and the insert block 301 are aligned, under the push of the first spring 304, the insert block 301 is inserted into the locking groove 501, locking the support block 5, thereby achieving a fixed connection between the fan and the quick-connect plate.

[0044] When fixing the fan, it is also necessary to connect the fan to a power source to ensure its normal operation. Therefore, a power socket 102, facing the fan, is fixed to the rear end of the fixing plate 1, and the power socket 102 is connected to the power source. Figure 11 as well as Figure 12 As shown, the rear end of the support frame 401 is provided with a plug 6 that is electrically connected to the fan body 4. The plug 6 is arranged facing the power socket 102, and the plug 6 and the power socket 102 are electrically connected by plugging and unplugging.

[0045] Furthermore, to increase the firmness of the connection between the plug 6 and the power socket 102 and avoid loose connections, the plug 6 is provided with a first spring seat 601 and a limiting baffle 603. The plug 6 passes through a through hole in the first spring baffle 403, which is fixedly connected to the support frame 401. The first spring seat 601 and the limiting baffle 603 are located on opposite sides of the first spring baffle 403. A second spring 7 is provided between the first spring seat 601 and the first spring baffle 403, sleeved on the plug 6. Under the push of the second spring 7, the plug 6 is more firmly connected to the power socket 102.

[0046] To prevent the plug 6 from rotating and causing misalignment between the plug 6 and the power socket 102, the plug 6 is wrapped with a hexagonal sleeve 602. The shape of the through hole on the first spring baffle 403 matches the hexagonal sleeve 602, thus ensuring that the plug 6 can only slide along its axial direction and cannot rotate.

[0047] Support platform, made of Figures 15 to 17 As shown, it includes a double-layer plate 8, an unlocking component and a fan mounting component that are slidably connected to the double-layer plate 8. The unlocking component is used to release the lock between the fan and the quick-release plate, and the fan mounting component is used to connect with the fan and pull the fan onto the double-layer plate 8.

[0048] The unlocking assembly on the double-layer plate 8 includes a first linear module 9 and an unlocking insert 10. The unlocking insert 10 is fixedly connected to the first sliding part 901 of the first linear module 9. Figure 18As shown, the unlocking plate 10 has an anti-interference groove 1001 recessed in the rearward side of the end facing the fan; When unlocking, the unlocking insert 10 moves and inserts between the outer block 303 and the outer side of the fixed frame 2. The first slide bar 302 slides inside the anti-interference groove 1001 and pushes the outer block 303 away from the fixed frame 2, so that the insert 301 moves out of the snap-fit ​​groove 501.

[0049] Depend on Figure 19 as well as Figure 20 As shown, the fan mounting assembly includes a servo motor 11, a screw 12, a slider 13, an L-shaped plate 104, and a rotating plate 15.

[0050] The screw 12 is coaxially and fixedly connected to the output shaft of the servo motor 11. The slider 13 is provided with a threaded hole and is threadedly connected to the screw 12. The double-layer plate 8 is provided with a slide rail 801, and the slider 13 is slidably connected to the slide rail 801.

[0051] The slider 13 is fixedly connected to the vertical surface of the L-shaped plate 14 via an extension rod. The middle area of ​​the rotating plate 15 is rotatably connected to the horizontal end of the L-shaped plate 14. An upper baffle 1401 protrudes above the horizontal end of the L-shaped plate 14. When the rotating plate 15 is in a vertical state, the end face facing the L-shaped plate 14 abuts against the upper baffle 1401.

[0052] The top of the rotating plate 15 is rotatably connected to a connecting rod 17, and an electromagnet 16 is fixed on the slider 13. The first telescopic rod 1601 of the electromagnet 16 is rotatably connected to the end of the connecting rod 17 away from the rotating plate 15.

[0053] During connection, the rotating screw 12 drives the slider 13 to move towards the fan. When the rotating plate 15, located below the horizontal plane of the L-shaped plate 14, abuts against the end face of the support frame 401, the slider 13 continues to move, the rotating plate 15 rotates, and the bottom moves upward until the rotating plate 15 moves directly above the connection slot 402. After the bottom is no longer obstructed, it reverses and returns to a vertical state. This causes the end of the support frame 401 corresponding to the connection slot 402 to be engaged in the U-shaped connection joint with the opening facing downward, formed by the L-shaped plate 14 and the rotating plate 15.

[0054] When the fan is pulled out, the unlocking plate 10 moves toward the fan and inserts between the outer block 303 and the fixed frame 2, causing the insert block 301 to move out of the snap-fit ​​groove 501. Then the screw 12 reverses, driving the slider 13 to move away from the fan. When the rotating plate 15 abuts against the edge of the mounting groove 402, it cannot rotate under the action of the upper baffle 1401, thus dragging the fan toward the double-layer plate 8, finally dragging the fan onto the double-layer plate 8, and then the unlocking plate 10 is reset.

[0055] Conversely, the fan on the double-layer plate 8 can be pushed onto the quick-connect plate and fixedly connected thereto.

[0056] When pulling out and resetting the fan, it is necessary to determine the relative positional relationship between the double-layer plate 8 and the fixed plate 1. In order to achieve this purpose, in this embodiment, the fixed plate 1 includes a horizontal plate fixed inside the fan mounting hole 3301 and a vertical plate located on the wall 33 below the fan mounting hole 3301. At least two positioning holes 101 are provided on the vertical plate.

[0057] Depend on Figure 17 As shown, a second spring baffle 802 and a limiting baffle 803 are provided in the middle layer of the double-layer plate 8. The limiting baffle 803 is closer to the fixed plate 1 than the second spring baffle 802. Coaxially arranged through holes are provided on the second spring baffle 802 and the limiting baffle 803, and a push rod 18 passes through the two through holes. A second spring seat 1801 is provided on the push rod 18, located between the second spring baffle 802 and the limiting baffle 803. A third spring 19 is sleeved on the push rod 18, located between the second spring seat 1801 and the second spring baffle 802.

[0058] A position detection device for the second spring seat 1801, such as a grating, is provided between the second spring baffle 802 and the limiting baffle 803, which can detect the position of the second spring seat 1801.

[0059] The positions of the second spring seat 1801 differ depending on whether the front end of the top rod 18 is unobstructed, abuts against the wall 33, abuts against the vertical plate of the fixing plate 1, or is inserted into the positioning hole 101. The position of the front end of the top rod 18 is detected by the second spring seat 1801. When the front end of the top rod 18 is inserted into the positioning hole 101, the support platform is in place, and the relevant procedures for pulling out or resetting the fan can be carried out.

[0060] The bottom moving assembly includes an interconnected telescopic assembly and a moving assembly, the top of which is connected to the support platform and controls the up and down movement of the support platform.

[0061] Depend on Figure 22 As shown, the telescopic assembly includes a vertically arranged multi-stage electric telescopic rod 20. The upper and lower ends of the multi-stage electric telescopic rod 20 are fixedly connected to the double-layer plate 8 and the base plate 22, respectively. The base plate 22 is slidably connected to the moving assembly. To enhance the fixing effect of the multi-stage electric telescopic rod 20, several inclined fastening rods 21 are provided between the fixing part of the multi-stage electric telescopic rod 20 and the base plate 22.

[0062] Depend on Figure 23 as well as Figure 24As shown, the movable assembly includes a platform 23, with casters 25 at the bottom of the platform 23. A movable groove 2301 is recessed on the top surface of the platform 23, and a second linear module 24 is inlaid at the bottom of the movable groove 2301. The second sliding part 2401 of the second linear module 24 is fixedly connected to the base plate 22. Both the second linear module 24 and the first linear module 9 are electrically powered linear modules.

[0063] During the disassembly and assembly of the fan, to prevent the platform 23 from moving, a stabilizing plate 26 is provided at the bottom of the platform 23 to slide vertically. A cylinder 27 and a compressed air pump 28 with an air tank are fixed above the platform 23. The exhaust pipe of the compressed air pump 28's air tank is connected to the intake pipe of the cylinder 27. The second telescopic rod 2701 of the cylinder 27 passes vertically downwards through the platform 23 and is fixedly connected to the stabilizing plate 26. To prevent the stabilizing plate 26 from rotating, a guide rod 2601 is vertically provided at the top of the top plate 26, passing through a through hole in the platform 23.

[0064] The platform 23 contains a power supply assembly and a control unit. The power supply assembly uses a rechargeable battery, and the control unit uses an industrial control chip. All electrical components contained in the support platform and the bottom moving assembly are connected to the control unit. The electrical connection method and control logic settings are all existing technologies.

[0065] A handrail 31 is provided on the platform 23, and a control panel 32 electrically connected to the control unit is provided on the handrail 31. The control buttons on the control panel 32 are used to control the corresponding electrical controls.

[0066] The double-layer plate 8 is moved up and down by a multi-stage electric telescopic rod 20, and moved left and right by a second linear module 24, thereby aligning the top rod 18 with the positioning hole 101. To ensure the distance between the double-layer plate 8 and the fixed plate 1, a top plate 29 is provided on the end face of the platform 23 facing the wall 33. A spring cavity 2302 is provided inside the platform 23, and an open slide groove 2303 is connected through the top of the spring cavity 2302.

[0067] A horizontally arranged second slide rod 2901 is fixed to the top plate 29. The end of the second slide rod 2901 passes through the spring cavity 2302 and is fixed to a third spring seat 2902. A viewing plate 2903 is fixed above the third spring seat 2902. The viewing plate 2903 slides inside the open slide groove 2303, and the top of the viewing plate 2903 extends to the outside of the platform 23. A fourth spring 30 is provided inside the spring cavity 2302.

[0068] When the platform 23 moves against the wall 33, the top plate 29 comes into contact with the wall 33. The platform 23 continues to move, and the top plate 29 compresses the fourth spring 30. The viewing plate 2903 moves towards the end of the open slide 2303 away from the wall 33. When the viewing plate 2903 comes into contact with the end of the open slide 2303 away from the wall 33, the gap between the double-layer plate 8 and the fixed plate 1 meets the requirements.

[0069] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
